Got dead domains that get a lot of spam?

[Marc Perkel]

Looking for people with dead domains that still get a lot of spam, 
especially spambot spam. I'm trying to get more spambot data for our 
hostkarma spam list. If you have such a domain that you aren't using can 
you set the MX to tarbaby.junkemailfilter.com. It will help stop 
spammers at the source.
